This invention relates to a spring structure for use in a mattress or. as a bed spring and which may also be used as an upholstery spring for. seat and back cushions.` v

An object ofthe invention is to provide a spring structure composed of bowed springs arrangedv throughout the area thereof which afford a resil-ient support providing iexibility and softness while producing a strongstable construction.

-Another object of the invention is to providea spring structure of said character. in which the bowed springs may be arranged within the assembly is contiguous or any desired apart relation in accordance with requirements andv which bowed springs may be vreadily replaced. without sacricing security, durability or stability. of the spring structure. f

Another object of the invention is to prov-ide a spring structure in which one end of each .of the bowed springs .is axed to a resilientcros's member while the opposite ends .of .the springs may be secured to any desired type of frame .or support.. Another object of the invention is to provide a spring structure of saidcharacterin which vthe upper and lower ends of the bowed springs are securely aiXed to frame members so as toprevent .canting or loosening of the springs.

Another object of the invention is to provider@ SI1-ring Sirlituleiii Which the springsiare secured .to cross members of a rigid foundation frame and at their upper; ends arefsecuredto f afresilient `frame consisting of crossed flexible springstrips.

Still another object of the] invention is to iproe vide Aa spring Vstructure in which the springs have onset bends at the opposite ends thereof which engage through openings inthe'cross members and cross. strips of the rigid andv flexible frames and with wire members extending throughv eyes formed by the protruding bends for securing the springs and the rigid and flexible frames together in assembled relation.

Still another object of the invention is to provide a spring structure of the character set forth in which a border wire is connected with theilds of the cross spring strips and-which oneof the strips at each intersection is depressed receive the other strip with means extending through the depressed vportions forVA securing `the cross strips together yet permitting of relative exing thereof at the intersections.

With the foregoing and other objects in View, reference is now made to the following specication and accompanying drawings in which the preferred embodiment of the invention is disclosed.

Fig. "7 is an enlarged fragmentary top plan view ofl one corner of, the` spring structure. .Referring to Ithe drawings by characters of reference,l the spring .structure includes longi+ tudinally and transversely extending rows of bowed or Senn-circular springs" Ill which are preferably fashioned -flroinflat spring. Vstock and have outwardly extendingfU-shaped bends II formed" intermediate the height thereof. lThe `said springs arevalso formed with iuawardly pro.- jecting transversely extending U-shaped bends I2 adjacent .the upper ends thereof and With downwardly lprojecting transv erselyv extending Us shaped bends I3 located adjacent thelower ends thereofA The spring structurealso includes a row of bowed or semi-circular springs I4 at the opposite ends thereof which have outwardly projecting U-shaped bends I5. intermediate the height ofv said yspring vand with upwardlyA projecting transversely extending LJ-shaped bendsi adje-.- centthe uDner-endsthereof. Y I. The said springs are arranged in spaced rela-'- tionthroughoutthearea ofthe spring structure and are disposed vbetween rigid andk resilient frames I1 and I8. The rigid frame I'Iconstitutes a support or foundation and includes a marginal frame I 9 and'spaced-parallelcross bars consiste ving o f \wooden bars 20 at the ends thereof and metal-lic; baits 9.2i. `intermedi atey the woodenl bars. ;rparginalframe I9 is preferably of angle iron leens i;ru ction which is arranged with a ange- 212 emxtendnginwardly, While the metallic crossbars -2-I1 repreferably ofinyerted U-shaped formation in the drawings;

in ,Grossesection with the .opposite ends thereof vflattened and welded or Aotherwise secured to the Yinwardly directedrllange 22 at' the opposite sides of the marginal frame r9. -Thewoodenta'rs 2t consist of at Wooden strips which are secured at their ends to the inwardly extending flanges 22 at the opposite sides of the marginal frame I9.

The wooden and metallic cross bars correspond in number to the number of transverse rows of the bowed springs I0 and I4 and the metallic cross bars 2I are formed with longitudinally ex- 3 tending slots 24 in the top walls thereof which slots correspond in number to the number of longitudinal rows of said bowed springs. The bowed springs I are disposed With the lower ends thereof arranged upon the top walls of the metallic cross bars 2| and with the downwardly projecting U-shaped bends I3 disposed in said slots 24 and protruding downwardly therethrough so as to form loops beneath the underside of the top walls. Stiff wire members 26 are provided which extend longitudinally of said cross bars beneath the top walls thereof and throughthe said loops for firmly securing the bowed springs I0 to the metallic cross bars 2I of the rigid frame I1. The bowed springs I4 in the transverse rows at the opposite ends of the spring structure are disposed with their lower ends arrangeduponv the wooden bars 20 and secured thereto by screws 21 or equivalent fastening means.

The resilient frame I8 consists of spaced transversely extending spring strips A29 which are crossed by spaced longitudinallyextending spring strips 30, the transversely extending springstrips 29 being disposed in superposed relation with reference to the crossbars and corresponding in number to the number of transverse rows of said bowed springs I0 and I4. At the junctures of the longitudinally and transversely extending spring strips, the longitudinally extending spring strips 30 are depressed to form shallow'rectangular U-shaped bends 3| for receiving the transversely extending strips 29 which are secured therein to connect the strips together by stiff wire members 32 extending longitudinally of the longitudinally extending strips 30 and through openings in the opposite legs of the shallow bends 3I thereof to dispose the wire members 32 above the transversely extending strips. f

The resilient frame I8 is disposed with the transversely extending spring strips 29 imposed upon the upper ends of the bowed springs I0 and I4. The said strips are formed with longitudinally extending spaced slots 33 through which the upwardly projecting U-shaped bends I2 and I6 of the bowed springs I0 and I4 protrude with the protruding upper portions thereof forming loops. Stiff wire members 34 extending longitudinally of the transversely extending strips 29 engage through the said loops for securing the bowed springs to the' resilient frame. The spring strips 29 and 30 are formed with 'rolled ends forming eyes 35 through which extends a border wire. 38 continuously about the periphery of the resilient frame I8 which border wire is located in alignment with the outer vertical flange 31 of the rigid frame I1. -1

Constructed in this :manner there is provided a spring structure which may be used in'a mattress asa resilient foundation for .a -layer Sofi' Soft material disposed. upon the flexible frame or which may be used as a bedspring to-support aimattress and which'. may also beu'sed as-an upholstery spring for seat and. back cushions. The flexible frame being of a resilient character will depress with the flexing of the springs so as to provide a comfortable support and the parts of the spring structure being connected -together by; wire members extending. .longitudinally o1' the supporting bars and strips retain the springs against lateral flexing or canting.

While stiff wire members 26` and 34 have been shown and described, the same may consist of a flexible cable extending longitudinally of the cross bars 2I and cross straps 29 and through the loops formed by the protruding portions of the U-shaped bends I3 and I2 for securing the springs I4 to the upper and lower frame structures, or the same may be secured by individual staples or clips extending through each of the said loops, or any equivalent fastening means.

What is claimed is:

1. In a spring structure, a rigid frame including a rigid border member extending peripherally about the frame and cross-bars connected at their ends to the opposite sides of said border member, a flexible frame consisting of longitudinally and transversely extending crossed flexible metallic strips, means connecting said strips for relative sliding movement, semi-circular spring members disposed between said rigid and flexible frames, said cross-bars and said transversely extending ilexible strips having slots opening therethrough and said spring members having U- shaped bends arranged to protrude through said slots, and wire members extending longitudinally of said cross-bars and of said transversely extending strips and through the loops of the protruding bends for securing the springs to said frames.

2. In a spring structure, a rigid frame including a rigid border member extending peripherally about the frame and cross-bars connected at their ends to the opposite sides of said border member, a flexible frame consisting of longitudinally and transversely extending crossed flexible metallic strips, means connecting said strips for relative sliding movement, semi-circular spring members disposed between said rigid and flexible frames, said cross-bars and said transversely extending flexible strips having slots opening. therethrough and said spring members having U-shaped bends arranged to protrude through said slots, wire members extending longitudinally of said cross-bars and of said transversely extending strips and through the loops of the protruding bends for securing the springs to said frames, and a, wire member extending peripherallyabout said flexible frame and secured to the ends of said longitudinally and transversely extending strips.
